Firefox (and Chrom{e,ium} AFAIK) can sync up your cookies, among other things.

but if you go this route, you have to share them with a third party (Mozilla or Google)?

Yes, but Firefox's Sync is open source [1], so you should be able to set up a private instance. IDK how easy or hard it is though.

Thanks for the suggestion. That wiki page brought me to https://mozilla-services.readthedocs.io/en/latest/howtos/run... which I intend to try out. I want to migrate my a Firefox profile from Windows to Linux and synching seems to be the easiest way to transfer bookmarks and saved passwords.
